Abstract:
... In this study, we compared the incidence of postharvest disease and the storage potential of blueberry fruit treated with thymol (inoculated with Aspergillus niger) with those in the control fruit during storage for 42 d at 2 °C. Treatment with 10–30 mg/L thymol was found to be more effective than treatment with higher thymol concentrations of 40–50 mg/L in terms of controlling Aspergillus niger-i ...

To control these mites, thymol is often used, although how it achieves this is not understood. One well-documented action of thymol is to modulate GABA-activated ion channels, which includes insect RDL receptors, a known insecticidal target. Here we have cloned two Varroa RDL subuni ...
